Abstract: Hadronic tag-side reconstruction is an important method for reconstructing B meson decays with missing energy. The Belle II hadronic tag-side reconstruction algorithm, Full Event Interpretation, relies on a hierarchical reconstruction of B meson decays with multivariate classification used at each stage. Given the large numbers of classifiers employed and decay chains reconstructed, the performance between the algorithm in data and simulation varies significantly. Here this effect is quantified in $34.6$ fb$^{-1}$ of data and correction factors are derived.
